This invent-ion relates to 7 draft, dust and weather eXcluders for hinged doors and windows, of the type comprising a member adapted to be turned upwards into an operative position about one of its edges,wh1ch acts as a fulcrum, by means provided on the door or window;

The object of the present invention is to provide an excluder of'simplified and improved Construction which, forcleaning or other purposes, will be capable of being lifted. freely out of a recess, serving normally to accommodate it, in the sill'of the door, and which will ofler no obstruction to the feet of persons passing through the doorway.

constructional embodiments of the Invention, as applied to an outside door and also tojan interior door, are illustrated, by way of example, in the annexed drawings. Fig; 1 is' a fragmentary elevation of the closed door with the weather-excluding member in its operative'or raised position;

' Fig. 2 is a section on the line 2'-2 in 1, the door being open, While Fig. 3 is a section on the same line with the door closed. I

Fig. l is'a fragn'ientary plan View, to a larger scale, of the door and thesill wherein said member is ,removably arranged.

"Fig. 5 is a fragmentary plan View correspondingzto Fig. 4,]but showing the door closed. I I

Fig. 6 1s a fragmentary sectional elevation showin the application of my inve'n I b e tion to an interior door.

Fig; 7 is a fragmentary sectional elevation of a door and" sill, and shows a modified form of weather-excluding arrangement;

Fig. 8 is a fragmentary sectional elevation of a further modification, Referring firstly to Figs."1"to5:-.

' A sill a isarranged outside and partly beneath the door Z) and is paralleltothe door when the latter is in its closed position.

An upstanding part 0 is formed atthe up per part of the sill and the latter is" also formed with a sloping recess (Z wherein a Weather-excluding member formed by a flat strip or plate e is loosely arranged. The top longitudinal edge of said plate is slightly below the top of the part c of the sill (see Fig. 2) and the ends of the plate e movably engage in recesses g formed in the two stiles g of the door frame, the obis being closed;

closed, see Fig. 4:.

ject of the recesses g beingto limit thefupward movement of the plate when the door Holes-2' are formed in the sill in order to drain off water lodging in the gutter-like lower part of the recess (2, said holes leading to the front face of the sill. A block or pintle g is secured to the bottom of the door with one side in the plane of the outside of the door and the other side in the plane of the hinged side of the door, said'pintle projecting below the bottom of the door and bein'g adapted to pass through a curved recess in formed 1n the part c of the Slll das the door is being hen the door is open the plate 6 rests in the recess (Z in the manner shown innFig. 2 with its top edge out of the way of the feet of persons passing through the doorway, but as the door isabout to close the projecting part of the pintle g catches the top edge ofthe plate and pivotsthe plate about its lower edge nntil, when the door is fully closed, sai d plate is raised substantially vertica-hsee Fig.6, and is prevented from further movement away from the door, by the front edgesof therecesses g In this position of *the plate its top I edge" rests against the door alongthe whole lengthiof the bottom thereof and wind, dust, rain and sleet are effectually pr'ei' entedfrom passing throughthe aperture between the bottom of the door andthe sillgowing'tothe plate cov-j ering said aperture A's appl ed to'an interior (100 115 plate a, see Fig; 6, is. arrangedinarecessl formed V ledges I:

to clear the sill a or the recess Z, the plate being then replaced.

In the modified construction illustrated in Fig. 7 the weather-excluding member 2 consists'of a long, fiat metallic plate, or strip,

weather-excluding plate can be readi 7 1y lifted out of the recess h, or l, in'order which is folded over uponitself. Near its' free end, the upper, folded-over portion 6 of said plate is first bent outward away from' 7* and s. The plate a is loosely arranged in I of pintle tion.

eluding flange s the plate p on the sill, as shown, the out wardly and forwardly projecting part of the upper portion 6 of the plate being arranged adjacent the flange s. Figure 8 shows a plate 9 which can be used instead Member 6 is removed.

lVhen the door is being closed, a pintle g thereon passes through a slot h in the part c of the sill and contacts with the plate e, turning the latterupward about the bottom longitudinal edge of edge bearing against the flange s of the member 7). WVhen the door is fully closed, as shown in the figure, the plate a is inclined thereto and rests thereagainst, and thus covers the aperture t between the bottom of the door and the "top of the sill. Moreover, when said plate is being turnedupward, the outwardly projecting part on the upper portion 0 thereof moves around the flange s of the member 7), its inner face contacting with the top of said flange when the plate is in its fullyinclined, or operative, posinus, in: order to penetrate to the back of the plate 6 drafts, dust and rain have first to pass the additional weather-exmeans formed by the contacting and outwardly and-forwardly proon the upper portion 6 of the plate secured to the outside of the door prevents any water, trickling down the'door, getting at the back of the plate 6.

The: sill a or the recessed part. Z thereof can be of metal instead of wood and'if desired the sill might be made hollow instead of solid, while flanges, or end-pieces, forming-stops for limiting the upward movement of theplate 0, could be provided on the ends of the sill, the recesses g then being eliminated The pintle g is shown of square section in Figs. 1 to 5 and 7 but it could be of .round or elliptical section or bell-shaped orbe replaced by a. roller or wheel;

It will be seen that in no construct-ion described above does the weather-excluding plate a vproject above the top of the sill or floor, wherein it is arranged, when the door jecting part plate 6. A

the portion 6 said,

sill,

1 against said is open and thus oflers no obstruction to the feet of persons passing through the door- Having now fully described'my invention whatl claiinand desire to secure by Letters Patent is I 1. A weather-excluding arrangement for hinged doors comprising, in combination, a door sill, at least one upwardly projecting flange in the sill, a freely removable doubled metallic strip loosely arranged on the sill, one edge of-said strip contacting with the upstanding flange to serve as a fulcrum \"l'1il8 the other edge projects outwardly and forwardly adjacent, the said upstanding plans and means on the door for turning the strip about its loosely hinged edge into its operative position'in which it is inclined to,

and rests against, the door when the latter is closed.

' 2, A weather-excluding arrangement for hinged doors comprising, in combination, a door sill, a recess in the sill formed by upstandingprojections extending along the a doubled metallic strip forming a wcather-excluding member loosely arranged in, and freely removable from, the'recess and one edge of said strip bearing as a fulcruni against one of said projections, and the other edge extending outwardly and forwardly adjacent the end of this projection and a member'on the the .door for engaging the weather-excluding member and turning it upward into its operative posi-- tion against the door as the latter is being closed. j v

3. r f,weather-excluding arrangement for hinged doors comprising, in combination, a door sill, an inclined recesstherein, an uprising projection along the base of said frecess, a freely removable doubled metallic strip loosely hinged throughout its length. in said recess with its'lower edgebearing projecting outwardly and forwardly adj aeent the end of this projection andits top edge not higher than the top 'ofthe sill, holes in said sill for draining off water lodgingin said recess, a pintle on the door, a curved slot in saidsill wherethrough the pintle moves, as the 'door is being closed, to engage I the strip and turn it upward about its bottom edge into its operative position, in which it is inclined to, and rests against, the door, and recesses in the stiles of the door frames for limiting the upward movementof said strip.

In testimony whereof I affix my signature.
